"We Know Our Onions" is the fourth episode of the sixth series of the British comedy series Dad's Army. It was originally transmitted on 21 November 1973. Synopsis The platoon take part in a Home Guard efficiency test. If the men pass with flying colours, they will be graded a 12-star platoon. Plot The platoon are examining their new Smith Gun (an artillery piece unique to the Home Guard), which they have to take on a Home Guard efficiency test for the weekend. Wilson is told off by Mainwaring when he complains "do we have to drag that gun about, what an awful fag".

The test is supervised by a Captain Ramsey, a tough, no-nonsense officer who berates the platoon for their shortcomings, particularly Pike, who is crying from his contact with the onions. Ramsey informs them that they will have to pass tests to be awarded stars, 12 being the maximum that can be earned. The first test requires the platoon to respond to role-playing scenarios. However, it does not go well for them as Wilson is so indifferent to the role-playing that it loses all effect, Jones attempts to throttle Ramsey when his back is turned (because he had told Jones he was going to be a Gestapo officer) and Wilson ruins Mainwaring's test by pointing out that Mainwaring wouldn't have to push anyone out of a declining
